CARBURETER.

Specification of Letters Patent.

Patented July 241, 1911 7.

Application filed December 22, 1915. Serial No. 68,140.

To all whom it may concern: I

Be it known that I. ROY N. CUNNINGHAM, citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Carburetors, of which the following is a specification.

This invention relates to apparatus for the production of a hydrocarbon vapor from liquid hydrocarbon by means of a current of air which is caused to travel through a tube or tubes containing fibrous material, the intent being to produce a very rich fuel mixture which can if necessary for the desired use be impoverished or diluted by the addition. of more air.

Means are provided for controlling the supply of liquid to the generating chamber according to the inlet of air, by means of a double valve as hereinafter described. Means are also provided for draining any uncombined liquid back to the main body of gasolene, in order to prevent flooding.

The air admitted to the device is fully loaded with the gasolene vapor by passing the same through a pipe or tube containing a series of baffle plates producing a tortuous passage, said passage containing fibrous material which produces a very effective vaporization or saturation. The apparatus is intended for use in a regular gasolene tank.

Further advantages of the apparatus will be apparent from the following description and accompanying drawings, in which,

Figure 1 is a vertical longitudinal section of the apparatus.

Fig. 2 is a section on the line 2-2 of Fi 1.

l ig. 3 is an enlarged detail of the valve. Fig. 4 is an enlarged detail of the baffle plate.

Referring specifically to the drawings, A indicates a tank for gasolene or the like, having a filling opening at 6. Within this tank are two pipes or chambers 10 and 10*, conveniently placed one above or beside the other, and connected to each other by a short pipe or opening 10. 7 is an air inlet pipe extending from the top of the tank to a valve casing 20 located at or communicating with the inlet end of the pipe 10. This casing is provided with a check valve 8 opening into the pipe 10, and the stem of this valve is connected to a needle valve 9 which controls the inlet opening for gasolene from the tank to said pipe. When by pressure produced by suction or otherwise the valve 8. is opened, the valve 9 is also opened, letting in a spray of gasolene from the tank. This valve can be regulated to control the amount of gasolene admitted at each operation.

The pipe 10 is provided, for most of its length, with a series of inclined baiiie plates 11 which extend alternately from the top and bottom thereof, producing alternate passages over and under said plates, and the intervening spaces or passages are filled with fibrous material indicated at 11*, said material being held in place by said baffle plates. The battle plates are elliptical in plan, with a notch or recess at the edge thereof, to form a passage through the plate. A perforated plate or screen 21 partitions the part of said pipe having the baffle plates and material from the vacant part or end 22 with which the connection 10 communicates. The upper pipe 10 is similarly provided with baflie plates 11*, fibrous packing 11, and an end chamber 22 partitioned off by the screen 21. The end chamber 22 communicates with a pipe 12 extending upwardly to a casing or chamber 13 located in the top of the tank, above the liquid level therein. This casing has a plurality of drain openings 13 'in the bottom thereof. An outlet pipe 14, for the vapor, extends into this casing, and has a plurality of openings 14 within said casing, and leads to an outlet 15 in the top of the tank. The valves 8 and 9 are normally closed by a spring 23.

The operation is as follows: Air is forced or drawn through the pipe 7 as by the suction of an engine, and the pressure thereof opens the valve 8 and the valve 9, the latter admitting a spray of gasolene which is taken up by the air and saturates the fibrous material 11 in the pipes referred to, producing a rich vapor which passes through the pipe 12 into the casing 13. Any uncombined or condensed liquid is deposited in the casing 13 and drains through the openings 13 back into the tank, the vapor passing out through the pipe 14. and outlet 15 to the place of use. This outlet is conveniently provided with a check valve.

By the means described the admission of gasolene through the valve 9 is automatic with the suction or flow of air through the inlet pipe 7 and the generating pipes, and by adjustment of the valve 9 the proportion of gasolene can be regulated to produce the best results, which are found to follow from a slight saturation of the fibrous material 11 The invention is not limited to the particular embodiment shown, but various changes may be made within the scope of the following claim.

What I claim as new is:

The combination of a tank for oil, a vaporizing conduit submerged in said tank and having an outlet for vapor at one end, an air inlet pipe extending downwardly into the tank and provided with a T-fitting one end of which has an opening from the tank, a

Copies of this patent may be obtained for and cooperating with said opening in the opposite end thereof.

In testimony whereof, I do affix my signature in presence of two witnesses.

ROY N. CUNNINGHAM.
